Why did the sunroof of my car shatter without warning?
Have you come across many cases of sunroofs shattering for no apparent reason whilst driving? This happened to my 2015 Renault Megane recently. The roof was closed at the time and I was travelling at 50mph - not a hot day. Now faced with bill to replace. Renault not interested in contributing.

It seems to be 'without warning' but it's actually because a stress fracture has set up unnoticed that weakens the glass, then, because it's actually a structural part of the car, running over a speed hump or pothole or anything that flexes the body then shatters the sunroof.
